JA, can you remember or have filed away what that measurement was on the Technics GaN flagship SU-R1 or the SU-R1000?

Cheers George

The SU-R1000 had 316mV of ultrasonic noise present at the loudspeaker outputs without the auxiliary Audio Precision low-pass filter. I didn't note the center frequency.

J.A.:"the three DC voltage levels described by the data are completely obscured by high-frequency noise, presumably radiated from the switching output stage. With undithered 24-bit data (fig.17), what should have been a relatively clean sinewave was again obscured by high-frequency noise. It should be noted however that the noise is above the audioband."

I would think that if the reviewer listen close he would have heard "artifacts" of this almost 1v noise through such efficient speakers as the 96dB DeVore Fidelity Orangutan O/96??

Cheers George

this is really depressing

Listen to what the man, JA, said.

I said "artefacts" of the fundamental.
(disappointing was used by him, not me)

“I compared the Technics's digital conversion to that of the Denafrips Ares II DAC, using a Sonore opticalRendu to convert the Ethernet stream to USB, the external DAC's output connected to one of the Technics's line inputs.”

Did you have occasion to play DSD files from the opticalRendu over the USB input? If so, did they play natively or did they play as DoP? I ask because I am having a tough time finding integrated amp USB inputs that can play native DSD without an ASIO driver, which Linux-based renderers like the Rendus cannot use.

Sonore has added some DAC IDs to its kernel, which is supposed to be the workaround, but I have found the implementation to be hit-or-miss. (For example, my ultraRendu is supposed to have the DAC ID for the NuPrime IDA-8’s DAC, but I can’t get dsf’s to play natively at all. That’s not necessarily an issue with DLNA players such as JRiver, Audirvāna, or MinimServer, but, with the expensive HQPlayer, I not only can’t upsample PCM to DSD, I end up with DSD downsampled to PCM.)

I know I can get external DACs that do just fine with USB and DSD from Linux, but, due to cabinet space considerations, I am in the market for an integrated that can handle these files natively.

I love reading all the reviews of Stereophile, it's a joy.

In al reviews this sentence in this review is one of the weirdest, puzzling and original ones I came across in years:

" translating analog to digital as smoothly as Rudy Van Gelder sipping a martini"

Haha, it should be added to the audiophile dictionary I suggest. But before that, shouldn't it be between quote signs because it is by Technics ? And what does it mean ?

Thank you
